I am completely in agreement that we should wear our very best clothing to Mass, to meet Christ our King. But there's nothing intrinsic about 1950's business attire (suit and tie) that makes it always and everywhere the best, much less the only, choice. Younger generations look on the old suit and tie as being excessively fake. They would only wear it ironically.
Don't you think the venerable suit and tie was a step down for some at the time? What, no hat? Not saying it should be worn inside the church building, but part of your wardrobe to the church. Besides, when you wear a hat you have something you can actively doff to show respect for the Blessed Sacrament, as well as any ladies you might pass. And what kind of immature boy doesn't have a gold watch on a chain, and a monocle? And what gentleman doesn't wear a white pair of gloves when motoring about? And make sure to grease your hair and wax your mustache when dressing up for church, at least on Sunday.
